WebAug 26, 2024 · Move two vertices parallelly to a diagonal, so that two sides become aligned with the other diagonal. This transformation does not change the area. Then move a vertex so that one side becomes aligned with the first diagonal. This transformation also preserves the area. The area is that of a triangle, half the cross-product of the diagonal vectors. WebThis suggests an inductive method of defining the determinant of any square matrix in terms of determinants ... Now expand this along the top row to get , the product of the main diagonal entries. A square matrix is called a if all entries above the main diagonal are zero (as in Example 3.1.9).
